I take home about $4,600 every month but my rent is $2,000 gas is almost $4 a gallon, I have a wife who is a stay at home mom and my daughter maxes out my medical copays at $1,500 a year. Water gas electric and sewer is about $200. Tv and internet is $0.15 every month. Cell phone for two lines is $80. So it adds up fast.
I also contribute about 10% to my 401k, taxes for state and fed are about 36%, medical is about $360 a month. I live cheap but still need to budget to stay on track.
The end of the month i usually put $200 into my savings and $100 is my entertainment which is equal to one family outing a month.
